A perfectly sealed bottle of water sits on the shelf at Target for many days at 20°C. When it was manufactured, it was filled 80% full and the remainder filled with air at 760 mm Hg.a. What does the phrase “many days” tell you about the system? b. What is the pressure in the “head space” of the bottle as it sits on the shelf at Target? c. What is the mole fraction of water in the “head space” of the bottle (i.e. the portion of the bottle that does not contain liquid)? d. Does your answer to c change if the bottle was initially 60% full of water?
